when using the zigzag stitch,why is the top stitch different than the back stitch on my B0 5 bernina

1 comments:
Mr. Anderson

The top stitch is different from the back stitch when using the zigzag stitch on the Bernette B05 Academy because of tension differences between the top and bobbin threads. Uneven tension can cause the top thread to pull too tightly or the bobbin thread to be too loose, affecting stitch appearance. Adjusting the thread tension settings properly can help balance the stitches.
